Unlike singlemode fiber, there is a dispersion or degradation of the signal after a certain distance depending on the grade of multimode fiber type. Thus, you’re most likely to find multimode cables in LAN backbones within individual buildings and singlemode cables in interbuilding connections or WANs (wide area networks). Reason being – the larger core diameter in multimode fiber cables allows for a greater number of signals/ rays of light to travel through at a time. Generally, singlemode cables should be used over long distances (greater than 500 m), whereas multimode cables should be used over short distances (less than 500 m). However, because singlemode fibers work with lasers that operate in wavelengths there is less attenuation or degradation of a signal, allowing transmissions to reach greater distances than with multimode fibers. Because of the core diameter of a singlemode fiber optic cable, only one signal/ray of light can pass through the fiber at a time. Fiber optic cable tool, Jonard Tools'Īnother difference between the two cables is the bandwidth capability.

Multimode fiber is preferred for shorter distances and tends to be easier to install due to its larger cores, which are easier to align. Multimode fiber optic cables feature a bigger core of 50 or 62.5 μm in diameter or larger that can support multiple data transmission modes. Singlemode fiber cables feature a smaller core from 8 to 10 micrometers can only support one type of data transmission mode and generally preferred for long-haul installations, and tend to be more expensive to install. So, what is the difference between singlemode and multimode fiber optic cables? Essentially, it all comes down to the core diameter of a fiber optic cable and signal dispersion over the length of the cable.ĭifference Between Single Mode Fiber and Multimode Fiber Optical Cable The buffer is a material that surrounds the cladding and protects the fiber from damage. The cladding is a material that surrounds the core and has a lower refractive index. The core is the central part of the fiber where the light travels.

With the increased demand for faster data speeds came the evolution of fiber optic cabling.įiber optic cable is made up of a core, cladding, and a buffer.

However, it wasn’t until the mid-1990s when the first fiber optic cables started to be installed for commercial and residential use and changed the internet to what it is today. We’ve heard this question asked so often that we decided to provide a brief description of the difference between the two, the similarities, as well as some common misconceptions about singlemode fiber and multimode fiber cables.Ī fiber optic cable or an optical fiber cable is a medium that is used for transmitting optical signals from one place to another that has a strand of glass fibers inside an insulated casing.įiber optic cabling has been in use in the United States since the mid-1970s, beginning primarily with government agencies.
